Baffle secured at a distance from the inner wall of a glass-lined container by means of a local connection

Abstract

The baffle ( 14 ) is fixed at a distance from the internal wall ( 12 ) facing a container ( 1 ) to be enamelled, for example a chemical reactor and is held separated from the internal wall ( 12 ) by way of at least one local connection ( 15 ). The baffle may be solid or hollow and in the latter case can be in fluid connection with the closed space ( 13 ) between the external wall ( 11 ) and the internal wall of the container at the local connection. The invention also relates to a container comprising one or several baffles of the type. The invention is of use in the chemical industry and in particular to the producers and users of baffles.
